Your skin, like your body, follows a circadian rhythm, with various functions peaking and dipping throughout the 24-hour cycle. Cell proliferation is highest at midnight and lowest at noon, blood flow decreases at night, oil production peaks midday, and skin pH becomes more acidic during sleep. Recognizing these natural cycles, Obagi® has launched Hydrate Luxe, a rich moisturizing cream designed to complement the skin’s nighttime renewal processes. This product contains ingredients like shea butter, mango butter, avocado, biomimetic peptides (which support nightly renewal and reduce the appearance of fine lines), and Hydromanil (for immediate and gradual moisturization). In a 2013 consumer survey, users reported improvements in fine lines, firmness, texture, radiance, and hydration after using Hydrate Luxe.
